Stations 194, 316, 331, 340, 355 : 160-300 fathoms. 



A specimen from Station 13 is rather larger than the type, being 6 mm. both 

 in height and greatest width.

Scala antarctica, Smith, " Discovery " Gastropoda, p. 8, pi. I, figs. 10-10i3 (1907). 



Station 294 : 158 fathoms. 



(July a single specimen, agreeing in all respects with the type from much 

 shallower water. 



8. Eulima exulata, u. sp. PI. I, fig. 2. 



Shell subulate, generally a little curved or exceutric towards the apex, white, 

 glossy ; whorls 9, slowly increasing, slightly convex ; suture a little oblique, narrowly 

 hyaline-margiuate ; aperture inversely auriform ; labrum (viewed laterally) promi- 

 nently curved, obscurely sinuate near the suture ; columella a little thickened, united 

 to the end of the labrum by a very thin callus. 



Length, 9 mm. ; diameter, 2 '75. 



Station 316 : 190-250 fathoms. 



Nine specimens containing the reddish animals. This is the largest of the 

 Antarctic species. The former lips are not observable unless very carefully looked 

 for. Although the spire is tapering, the apex is not acuminate. 



9. Eulima N<>litria, u. sp. PI. I, fig. 3. 



Shell small, white, shining, somewhat curved, consisting of seven slightly convex 

 whorls which increase gradually and are separated by an almost horizontal suture, very 

 narrowly hyaline-margined beneath. Spire slightly arcuate with an oblique obtuse 

 apex ; aperture inversely auriform, about one-third the length of the shell ; columella 

 straightish, united above to the outer lip by a thin callus. 



Length, 4 mm. ; diameter, 1 5. 



Station 331 : 250 fathoms. 



A single specimen. Differing from the known Antarctic forms by its curved 

 growth, form of the aperture, etc.
